Outdoor Unit Multi-Zone Ductless Heat Pump System Standard Heat 18,000 BTU 208/230V DLCMRAH18BAK

The Outdoor Unit Multi-Zone Ductless Heat Pump System Standard Heat 18,000 BTU 208/230-1-60 (DLCMRAH18BAK) is an OEM ICP variable-speed inverter outdoor unit engineered for multi-zone ductless comfort systems where standard heating and cooling performance is required without specialized low-ambient or high-heat features. With a nominal 18,000 BTU capacity and single-phase 208/230 V power, this unit distributes modulated capacity across connected indoor units using inverter compressor control and matched controls to maintain balanced comfort. It is suited for residential or light commercial applications that operate primarily in moderate climates and do not demand extended low-ambient heat performance. For proper job fit, technicians must verify approved indoor unit combinations and total connected tonnage, confirm the correct refrigerant line sizes and allowable piping lengths per installation instructions, and ensure that the service electrical supply is 208/230 V single-phase with correct overcurrent protection. Correct system matching supports efficient operation, reliable communication between indoor and outdoor units, and a reduction in capacity imbalance or mis-connection callbacks.
